Re: (unknown)

Dear Filippo,

The genus Dietes was erected in 1866 and includes plants that were formerly included in either Iris or Moraea or Naron.   There are six specicies – D. bicolor, D. butcheriana, D. flavida, D. grandiflora, D. iridoides, and D. robinsoniana – all visually distinct, except for D. grandiflora which looks like D.iridoides.  The difference is that D. grandiflora flowers last several days while those of D. iridoides last only one day.  Both plants are sold under both names as well as under the invalid name D. vegata.  Clive Innes in The World of Iridaceae indicates that the two are possibly synonymous.  At any rate, the flowers are variable enough so that if your plant looks somewhat different from the photo in some list, it doesn’t necessarily mean that your plant belongs to another species.

 

As to the photos of Dietes vegata in the Iris Species Database, there is no doubt that they are D.grandiflora.

 

Moraea vegata is a totally different species, not to be confused with any species of Dietes.

Dear David,
 
it's not so strange if there are some mistakes in the Database, as everybody can upload his own informations to the site.
It would be helpful if someone can confirm or not the new uploads (on the basys of the official checklist and nomenclature) .
 
Bob, Dennis, what do you think? Too much work, maybe...
 
Anyway, I think Dietes vegeta doesn't exist. I know (and grow) a Moraea vegeta, but never heard about Dietes with the same name, except for old and erroneus synonims.
I grow in my garden only 4 species of Dietes: grandiflora, iridioides, bicolor and robinsoniana. All these 4 species are really different each other in habitus and no one of them is similar to the "vegeta" shown on the Database.
The first 3 species are from central-south Africa, and D. robinsoniana (the bigger of the genus) if from the Lord Howe Island, near Australia.
 
About Neomarica I can't say more. I grow only N. candida and N. caerulea, so I don't know the other species.
